MANIFOLD.

Application filed December 24, 1924. Serial No. 757,964.

To all whom t may concern.'

Be it known that I, MniiviN SOLOMON GROH, a citizen of Canada, residing at Toronto, in the county of York, in the Province of Ontario, Canada, have invented a new and useful Improvement in Manifolds, of which the following' is a specification.

My invention .relates to manifolds which will fill or empty an operating' machine with any desired fluid, which will also permit` normal operation of said Operating machine l whenever desired, and which will be of simpler and more efficient construction than any manifolds heretofore in use.

I attain these Objects by the :mechanism illustrated in the accompanying drawingsj in which:

Fig. l is a side view of my device; Fig. 2 is another side view of my device showing` a portion thereof in sectiongFig. 3 is an end view of my device; and Fig. l is a top view of my device.

Similar letters refer to similar'v parts throughout the severa-l views:

A is the cross channel; B is a plate integral with cross channel A, and adapted to bolt the` same in any convenient position; C is the intake line; O1 is a threaded lug' to hold stuffing box O3; O2 is a needle valve to open or close the connection' between cross channel A and intake line O; -D is thc delivery line; D1 is the threaded lug),` to hold stalling box D3; D2 is a needle valve to open or close the connection between cross channel A' and delivery line D. A1 is a tap in the end of cross channel A, adapted to -be plugged in the usual manner by a threaded plug A2.

The operation of' my device is as follows:

When it is desired to fill the Operating,F machine with a fluid, vremove threaded plug A2, close valve'DZ, open valve O2, and inject the fluid through threaded Opening A1 into cross channel A, thus filling intake line AO by means of opened valve O2, and continue this filling process until the desired amount of fluid has been injected into the Operating machine. Then insertplug A2 tightly into tap A1, then close valve-O2. The operating' machine is then in condition to function normally with intake line O and delivery -to said cross channel and connected to said cross cliannelbya substantially smaller coin-- necting channel, said connectingchanncl being adapted to be opened or closed bv a needle valve; and a delivery line substantiah ly at right angles to said cross channel and connected tO ysaid vcross channel by a substantially smaller connecting channel, said connecting channel ,being adapted to be opened or closed by a needle valve; said iiitake line and said delivery line each being adapted to circulate their contents independently when their respective needle valves are closed with relation to the ycross channel. y v
